An Emeryville man, Alexander Yohn, was arrested after allegedly crashing his Mini Cooper into Silva’s motorcycle and then into a utility pole. Police say officers took the 23-year-old into custody in a nearby field.

Witnesses say earlier Yohn had been acting belligerently and appearing intoxicated at a Taco Bell restaurant.

He was booked on suspicion of gross vehicular manslaughter while intoxicated and hit-and-run causing death or injury.

Silva was a Marine lance corporal who had returned from Afghanistan in February.
